The bigger cooler can hold 37.5 gallons and smaller cooler can hold 7.5 gallons.
Step-by-step explanation:
Given,
Gallons needed for party = 45 gallons
Let,
x represents the gallons hold by large cooler
y represent the gallons hold by small cooler
According to given statement;
x+y=45 Eqn 1
x = 5y Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 6

Putting y=7.5 in Eqn 2

The bigger cooler can hold 37.5 gallons and smaller cooler can hold 7.5 gallons.
